exim-elspy-debian: Exim with elspy for Debian GNU/Linux

I have prepared an Exim package for Debian GNU/Linux that differs
from the standard Exim 4 packages (exim4-base, exim4-daemon-*, etc.) in
a number of important ways:

no configuration files: if you install this package on a bare
system, Exim will be inoperable. You must create
/etc/exim/exim.conf (or
/etc/exim/exim4.conf) manually.

includes elspy, which
lets you write local_scan() functions in Python
instead of C

exim binary dynamically linked with Python 2.3 so
elspy can work

also built with GNU TLS and Berkeley DB 4.1 support

I am greatly indebted to the standard Debian packages for Exim 4;
without the fine work done by the Debian Exim maintainers, I never would
have been able to pull this off. (After all, most of what I did was
remove functionality from their package in order to create what I
wanted.)

Using the Package

I built this package for my own use and for the mail service on
starship.python.net. I think a couple of other Exim/Debian/Python fans
use it too. If you would like to use my package, just add these two
lines to /etc/apt/sources.list:

set the environment variable ELSPY to point to the
elspy sources and build your own Exim packages,

export ELSPY=/tmp/elspy
dpkg-buildpackage -i -rfakeroot -sd -us -uc

(-sd tells dpkg-buildpackage not to include the
original source, since I don't want it in my repository.
-us and -uc turn off signing
the packages, since I haven't bothered to figure out package
signing. Obviously, you can leave those options off if you like.)
